Simulation of Molecular Weight Distributions Obtained by Pulsed Laser Polymerization (PLP): New Analytical Expressions Including Intramolecular Chain Transfer to the Polymer

A new approach for the simulation of PLP (pulsed laser polymerization) is presented. This approach allows one to obtain new analytical solutions for different polymerization schemes, including either chain transfer to the monomer or intramolecular chain transfer to the polymer. The first results of the simulation of PLP experiments on n-butyl acrylate at 20 °C and ambient pressure are presented

Determination of Propagation Rate Coefficient of Acrylates by Pulsed-Laser Polymerization in the Presence of Intramolecular Chain Transfer to Polymer

Unusual difficulties are faced in the determination of propagation rate coefficients kp of acrylates determined in PLP experiments for different frequencies should range between kp (propagation rate coefficient of the secondary radicals) at high frequency and kp av at low frequency. The kp av value could be expressed from kinetic parameters: kp av = kp - kp-kp2/1 + kp2[M]/kfp, where k fp is the backbiting rate coefficient, kp2 is the propagation rate coefficient of midchain radicals, and [M] is the monomer concentration. Apparent propagation rate coefficients determined for different frequencies by simulating the PLP of N-butyl acrylate at 20 °C. Horizontal full lines show the values of kp and kp av
